Customer Number and Device Type Count in the CSV Export

In the device list, the customer number from the “Reference No.” field of the assigned customer should be displayed as an additional column and included in the CSV export.

In the customer overview, additional count columns should be available for individual device types such as switches, firewalls, and printers, and these should be exportable along with the customer number.

Both CSV exports should cover all authorized customers collectively, without having to export each customer individually.
